The isolation of target cells from biological samples such as serum, urine or blood in high-throughput manner without contamination with other cells is the starting point of developing effective therapy for many diseases. Currently available methods for cell isolation/separation require extra labeling. Furthermore, separating target cells using current methods do not produce pure target cell ...

At the micron-level, thermal actuation exerts larger forces compared to the widely-used electrostatic actuation. To obtain large displacements at low voltage the principle of Electro Thermal actuation is used. It works on the principle of selective non-uniform Joule heating which results in thermal expansion due to constraints. The Microgripper presented here is studied and analyzed by carrying ...

Power cable manufacturing is limited by the maximum length of cable that can be produced and stored on cable drums. This creates a need or rather an opportunity for a cable accessory, namely 'Cable Joints'. Joints are an impeccable component in the power cable network that necessitate extreme care in their design and installation in order to facilitate a smooth connection between two cable ends ...

The coaxial magnetic gear is a good alternative to classic mechanical gears. The magnetic gear has high mechanical durability, overload protection and lower noise, than a mechanical gear [1,2]. A static model of a magnetic gear [3,4] is used for simulation of the magnetic fields and mechanical forces in the steady state. For the dynamic characteristic of the magnetic gear, i.e. a run-up, slowing ...

We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered in order to design a model tacking account of the skin depth and the incident wavelength, keeping a constant ...

As the importance of nanoparticles is growing more and more, controlling and understanding the properties of nanoparticles became a focus of research. In this field Meyer at al. [1] are researching the GMR effect in granular gels to develop magnetoresistive sensors. The GMR in granular gels is simulated to investigate the physical processes in those systems. As soon as the models coincide with ...

Superparamagnetic micro beads offer some attractive applications in biological and biomedical fields. Some of the important applications include manipulation and separation of cells, isolation of specific cells, active drug delivery, magnetic cell separation, separation of proteins, and application of mechanical forces to cells, etc. A COMSOL Multiphysics model is developed in 2D ...

Power grid voltages and currents may be distorted due to presence of harmonics. Measurements of such voltage with harmonics may be performed using newly developed instrument with a small air-core transformer based probe as the input unit. The probe must be shielded against unknown external electromagnetic fields. At the same time, the probe must remain linear throughout the range of frequencies. ...

High temperature super conducting (HTS) cables are gaining attentions for their ability to transmit more power compared to their convention counterparts with essentially no resistance and electromagnetic emissions. They are also appropriate for solving the grid congestion problem in the power corridors with their reduced size and weight. But the AC loss that occurs in the HTS cables reduces the ...

The TS (Turin Shroud) [1,2] is a fine linen fabric showing a not yet explainable [3] double body image of a scourged and crucified man stabbed on the side. Many hypotheses have been formulated without success [4] and perhaps the most reliable is one correlated to the Corona Discharge [5] that supposes the presence of an intense electric field, amplified by the presence of ionization induced by ...
